Abstract Psychedelic drug use is experiencing a global resurgence, both in clinical research and community settings. This paper presents a comprehensive public health analysis of the naturalistic use of psychedelics—defined as use outside clinical or research environments. Drawing on a review of 104 peer-reviewed articles, this analysis evaluates the mental, physical, and social outcomes...
ABSTRACT Three novel 14 C‐labelled isotopologues of the psychoactive agents psilocin, psilocybin and 5‐methoxy‐ N , N ‐dimethyltryptamine (5‐MeO‐DMT) were synthesised, all labelled at the 2‐position of the indole. The syntheses involved incorporating the 3‐dimethylaminoethyl substituent common to all three substances onto a 4‐ or 5‐substituted indole intermediate via successive treatments with...

The use of drugs with psychedelic and dissociative effects for the treatment of psychiatric illnesses has become increasingly popular in recent years. However, few trials have been conducted to determine the efficacy of these agents in the specific setting of treatment-resistant major depressive disorder (MDD) in older adults. In this paper, we review notable aspects of treatment-resistant MDD...
Serotonergic psychedelic drugs are under investigation as therapies for various psychiatric disorders, including major depression. Although serotonergic psychedelic drugs are 5-HT2A receptor agonists, some such agonists are not psychedelic, potentially due to differences in 5-HT2A receptor ligand bias or signalling efficacy. Here, we investigated 5-HT2A receptor signalling properties of...
Background: Mindfulness and compassion are therapeutically relevant and can be increased through different forms of meditation practices. However, meditation practice needs time and commitment. These resources are often limited in patients with mood disorders. Therefore, efficacious remedies that increase mindfulness and compassion could provide therapeutic options. This study aimed to...

Millions worldwide suffer from chronic pain, a complex condition often accompanied by depression and anxiety, highlighting the urgent need for innovative treatments. Classic psychedelics, including psilocybin, lysergic acid diethylamide (LSD), and N,N-dimethyltryptamine (DMT), primarily act on serotonin 5-HT2A receptors and have emerged as potential modulators of pain perception and mood...
Request for Proposals - Exploring expanded consciousness and endogenous DMT Sponsor: DMT Quest Aim of Funding This funding seeks to advance scientific understanding of consciousness, human potential, and the mechanisms underlying expanded awareness. Eligible research may investigate endogenous N,N-dimethyltryptamine (DMT) and its role in human consciousness, but we also welcome innovative...
Over the past decade, research with psychedelics has gained new momentum, leading to a psychedelic renaissance in both basic and clinical research. Among these substances is ayahuasca, an Amazonian plant medicine used for millennia by indigenous people for ritualistic and healing practices, which has recently entered research labs in the Americas and Europe. Preliminary findings indicate its...
Psychedelics are known to profoundly alter perception and self-referential processing, yet their specific effects on face recognition -particularly with regard to the recognition of face familiarity-remain underexplored. This study investigates the effects of an ayahuasca-inspired novel DMT/HAR (N,N-dimethyltryptamine/Harmine) formulation and Harmine alone on face recognition and...
